Flashcards in Shock Deck (12):
1

Alpha-Adrenergic Activation

Upon circulatory failure, causes venular constriction which increases filtration out of capillaries, exacerbating shock

2

2 Pathogenic Mechs of Arteriovenous Shunting & Which Shock Observed

Sludging of blood in caps cause it to go through metarterioles
Loss of arteriolar/venous resistance which makes capillary bed ineffective filter
Seen in septic shock

3

4 Classifications of Shock

Hypovolemic
Cardiogenic
Obstructive
Distributive

4

Distributive Shock

Changes in vascular resistance or capillary permeability, like sepsis, anaphylaxis, neurogenic, etc.

5

Systemic Inflammatory Response Syndrome (pop at risk and 4 effects)

Common in IS pts, w/ sepsis release shit like LPS and stimulate TNF and IL1. These lead to vasodilation/decreased PVR, so increase in CO and low BP. Also Myocardial depression so decrease EF. Also increase NO production. Also complement cause increase permeability and cause leakage to EC space (warm shock, extremities warm despite low BP)

6

Heart Complication from Shock

Decrease coronary flow, thus increasing myocardial dysfunction

7

Adult Respiratory Distress Syndrome

Pulmonary capillary dysfunction from shock leading to edema and acute respiratory failure

8

Hypovolemic Shock (RA, PCW (like LAFP), CO, SVR)

Low, Low, Low, High

9

Cardiogenic Shock (RA, PCW (like LAFP), CO, SVR)

Variable, High, Low, High

10

Septic Shock (RA, PCW (like LAFP), CO, SVR)

Low, Low, High (symp stimulation), Low

11

Sepsis + Hydration (RA, PCW (like LAFP), CO, SVR)

Normal, Normal, High, Low

12

Big Teller of Septic Shock

Warm skin w/ low BP
